We
live in the machine age and depend on machines in almost every
activity of our daily lives.A
machine is a tool used to make work easier. Simple machines are
simple tools used to make work easier. Compound machines have two
or more simple machines working together. Many tasks such as lifting a heavy

Material and instructions: In this project you
will design and construct a machine that can lift a heavy object with a
force less than the weight of the object.
